Jazz Tangcay Artisans Editor SPOILER ALERT: This interview contains spoilers for “Central,” the fifth episode of “Expats,” now streaming on Prime Video. Lulu Wang’s “Expats” steps into feature-length territory for this week’s episode, which focuses on the working class women by diving into the lives of the help, Essie (Ruby Ruiz) and Puri (Amelyn Pardenilla). The story steps away from the wealthy world of Margaret (Nicole Kidman) and Hillary (Sarayu Blue), instead following Essie and Puri on their day off, unwinding from their hectic work.
